How to Repair a Motorcycle Exhaust
If you have a motorcycle with a dented exhaust pipe, you can easily repair it yourself without spending a great deal of money. With just a few tools and some time, youre motorcycle exhaust will be fixed in no time. In most cases, you will be able to restore the exhaust shape by as much as 95 percent, which isnt perfect, but is quite an improvement.
Instructions
- 1
Run water through the entire exhaust system two or three times in order to ensure that its clear of fresh gas deposits (if the exhaust has excessive carbon deposits, remove all previous deposits before pressurization). Seal both ends of the exhaust and tighten the expansion block plugs (the expansion block plugs should be located far enough in to attach vice grips on each end of the exhaust). Attach the vice grips (one small one on each end).
2Hook the exhaust pipe up to an air compressor before pressurizing the system. Pressurize the system (between 80 and 120 PSI). Heat each dented area with the map gas system to a red glow slowly (the dents may start to come out), keeping the heated area pointed away from you. Tap out the dents (moving in circles around dented area) with your hammer.
3If the seams split due to excessive heat, use the welder to seam the splits back together. If you are not well-versed in the use of a welder, you may have to take the exhaust to someone who can do this portion for you. Turn on the drill with the wire wheel attachment. Apply the wheel with a great deal of pressure to any areas that are discolored until the discoloration is reduced or completely removed. Polish the exhaust using a clean towel to remove any final discoloration.
